Tried with MonoTouch 6.0.4 / MonoDevelop 22.214.171.124 and MonoTouch 6.0.6 / MonoDevelop 3.0.5.
error MT0000: Unexpected error - Please file a bug report at http://bugzilla.xamarin.com
System.NullReferenceException: Object reference not set to an instance of an object
at MTouch.Main2 (System.String args) [0x00000] in <filename unknown>:0
at MTouch.Main (System.String args) [0x00000] in <filename unknown>:0
Steps to reproduce:
1. Check out: https://github.com/scarnie/MvvmCross
2. Ensure you're on vNext branch (default)
3. Open MvvmCross_All solution
4. Ignore errors for Android and Windows builds
5. Find the Tutorial.UI.Touch project
6. RMB and Build
This error will occur.
There's a reference to System.Windows (which MonoTouch doesn't have).
Does removing that reference fix the problem for you?
There is a type forwarding assembly in the solution. The project is called System.Windows.Touch, which generates System.Windows.dll. If I remove the missing one it does indeed compile correctly.
Closing this then.
We've already implemented better error reporting, for later releases we'll tell you what's wrong instead of throwing a NullReferenceException.
